Research partnership helps ocean industries

MetOcean Solutions and the Coastal and Regional Oceanography Group in the School of Mathematics and Statistics at the University of New South Wales (UNSW) are partnering to ensure that marine industries will benefit from the latest ocean research along the southeast coast of Australia.

“The science team at UNSW produces world-class research. By combining their ocean data and models with MetOcean Solutions’ operational experience we will provide an even better service for clients along the New South Wales coast,” says Prof Moninya Roughan, MetOcean Solutions' Chief Scientist and UNSW`s Coastal Oceanography Group Leader. “This collaboration helps make oceanographic research useable, making valuable knowledge easily accessible to marine industries and the public, and improving safety and efficiency at sea.”

The UNSW team developed a 23-year (1994-2016) hydrodynamic hindcast model using the 3D Regional Ocean Modeling System (ROMS). The model simulates ocean circulation at sufficient resolution (2.5-6 km) to characterise the hydrodynamics in the region. Results have been validated with quality, long-term oceanographic data, and were distributed through the Australian Integrated Marine Observing Program (NSW-IMOS).

The MetOcean Solutions team use model output to generate statistics needed by clients for design purposes. In addition they have characterised the coastal marine environment at a number of locations along the coast of SE Australia, and are conducting research that will improve understanding of dynamical drivers of the coastal circulation. The data has also been used to provide boundary conditions to clients for further downscaling studies.

“Using the UNSW regional model ensures we are providing the highest quality information for our clients,” says MetOcean Solutions Forecast Operations Manager Dr Rafael Soutelino. “We are very enthusiastic about working with UNSW, and all the improvements we can achieve for industries and governments operating at sea in the region.”

UNSW`s oceanography group has been studying the East Australian Current (EAC) for decades, collecting valuable in-situ data and developing a suite of high-resolution numerical ocean models for the region. The EAC is the Western Boundary Current of the South Pacific subtropical gyre that flows south along the east coast of Australia, dominating the coastal circulation from Brisbane to Tasmania.

“The EAC is characterised by high eddy variability and the correct representation of these eddies into nearshore hydrodynamic models is critical,” says Dr. Colette Kerry, Postdoctoral Research Associate in the School of Mathematics and Statistics at UNSW. “Advancing our understanding of the dynamics of the EAC will help improve model predictions.”
